Erm. Yes well, it was out there now, wasn't it?
"Yes. I've been offered a job at the Wizarding University of Cairo." It paid a LOT more and meant he wouldn't have to put up with the whole... thing... with Hecate. Odd situation and just another example of how your impressions of a person could change over time and how you could think so well of someone and then they end up being a huge disappointment.
"Considering the reason I was.... replaced as your head of house, its really only a matter of time before the board of governors decide to move on that and fire me. Again." Eh. "I'd much rather choose to leave, though I hate the thought of leaving any of you behind." And at risk of losing body parts or worse.
Surely Hecate would be on her best behaviour now though?
"And as for which friend..." He eyed Trixie. "The former Herbology Professor, Anastasia Bunbury, who I attended the Alumni Ball with." They'd been together for... a long while now. Technically longer than the Lawsons. Hmm.
"You'll come back refreshed though, Trixie." He told her. "After summer you'll be ready to go, and see all your friends again. And you can always write to me. I'll write back of course."
And Violet.
More hugging.
Awkwardly he patted her arm.
"Well, I don't want to leave all of you either. But it is something I need to do for myself. And you're doing so well now, you're very strong and intelligent. A brilliant Slytherin and I admire how far you have come, and know you have so much further to go and you can do it. You can write to me if you wish."
Oh yes. The boss.
Well, he supposed that Tate ought to know.
"Casey." Ahem. "I resign."
That'd do it.
